Rules for Posting Guides on Our Community
1. Defining a Guide Guides are comprehensive reference materials, how-tos, or comparison tables. A guide must be well-organized both in content and layout. Information should be easily accessible without unnecessary navigation. Guides can include flowcharts, step-by-step instructions, or visual references that compare different elements side by side.
2. Infographic Guidelines Infographics are permitted if they are educational and informative. They should aim to convey complex information visually and clearly. However, infographics that primarily serve as visual essays without structured guidance will be subject to removal.
3. Grey Area Moderators may use discretion when deciding to remove posts. If in doubt, message us or use downvotes for content you find inappropriate.
4. Source Attribution If you know the original source of a guide, share it in the comments to credit the creators.
5. Diverse Content To keep our community engaging, avoid saturating the feed with similar topics. Excessive posts on a single topic may be moderated to maintain diversity.
6. Verify in Comments Always check the comments for additional insights or corrections. Moderators rely on community expertise for accuracy.

my pc case shocked me when I touched it, not a huge shock like live wires but enough for you to feel a little pain (like static shock on winter day). My phone charger also shocked me the same way when i touched the metal part of the USB head.
yea PC power supplies do need the earth pin, but i'm surprised the usb also shocked you, maybe a faulty adapter?
It's a $80 GAN charger from Ugreen and the C-to-C cable that came with my iPhone.
I would be a big sad chump if it's a faulty brick. But thanks, I'll find a way to troubleshoot that.
If it shocked you, it's faulty
